Chemical Structure
Description
As a certified reference material (CRM), Candesartan Cilexetil Impurity 29 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies Candesartan Cilexetil Impurity 29 (CAS 16533-45-2), a pharmacopoeial impurity reference standard (molecular formula C10H9NO6, MW 239.18 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C10H9NO6, Candesartan Cilexetil Impurity 29 contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 239.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
